The Doctor Falls is the best season Finale from Doctor Who. The payoffs are brilliant, the stakes are real, and the ending is one of the most memorable in Doctor Who history. Although Bill’s exit from the show could have been handled better, the interplay between The Doctor, The Master and Missy can’t be beat. Overall this is a fitting end to the series.

The Pyramid at the End of the World fails to live up to its predecessor, Extremis. But that doesn’t mean it’s a bad episode. Pyramid is not the action packed invasion story we were expecting, instead it’s something deeper. The question is not “How will The Doctor prevent the invasion?” but “How will humanity cause it’s own destruction?” Although the crisis was a bit of a let-down, the ending itself was a quintessential Dr Who ending.

Extremis dispatches with the rather tired monster of the week format while finally giving us the big reveal of the series: the answer to who is inside The Doctor’s box. With a truly intriguing premise and what appears to be a villain able to match wits with The Doctor, Extremis is the best episode of this series to date.

“Oxygen” is a breath of fresh air coming on the heels of last week’s “Knock, Knock”. A suspenseful space adventure, the only letdown is the fact that the mystery of “The Vault” has yet to be fully explored.
